Tape or disk for backup and data recovery?


His backup and archiving can a nightmare as suits the needs for instant access against the equally important need to balance security and trust? Data loss is one of the events quickly where to get IT professional's life by one the systems can rotate applause for how well a run where may threaten your whole career.

What is the best system use? Disk-based easy access systems are a better option than tapes and tape libraries or are the methods of the traditional data backup and recovery a better bet for long term data security?Each technology has its power and its Gegner.Band will easily a user friendly by many to be slow and inflexible terms while disk-based systems to use backup system with the ability to add that require a dynamic filing system additional functions such as deduplication.

In addition the current cost of hard drives, a 1.5 TB hard disk costs are not much more than a 1.6 TB LTO-4 tape, and tape capacity based on average data is compressibility, the native capacity 800 GB and disk is no longer does this mean the expensive Cousin.So, the band goes the way of the Dodo, and that the future is disk-based? is the question, "What is the purpose of our backup system".

Is it easier?

A system easy to use and manage operational is a better choice than one that is cumbersome or complicated. It also means that backs up get the most robust method falls apart when nobody used it.So, if you have users with laptops, real efforts over the Internet quickly start a backup with no, it will happen, and you're much less likely that your to find themselves at the mercy of data recovery company.

Is it manageable?

The disadvantage of using everything without any thought to back up and you end up with a Alptraum.Right though to get the guidelines to facilitate is too simple overuse and Missbrauch.Machen life for people, and all should be good.A dynamic filing system allows deduplication and single instance-implement memory so that the actual footprint is minimized.

It provides business continuity?

In most cases, that the disk-based system over the other options can win the data of again effectively online, or at least near Line.Der is recovering data after an accidental deletion of damage which should is nagging your IT Department before the data at the location is not too arduous, and not several days.

So, get rid of the tape?

Not so fast.You online backup and the clever advanced disk-based storage could comfort and an immediate result when there are minor issues, but what happens if the problems are severe or the request for data is external, in connection with banking regulation or another aspect of compliance?

The effort the tapes, cataloging an ordeal seems less you and restore necessary if a Wipeout for example after a fire or a flood or a total system failure.The fact that send the backup tapes from the external memory and you get up and running all that what counts is again.Even if the above site backup tapes under a few meters water been dipped, the chances of a full data recovery are good, far better than for each hard disk, especially one still rotate was those when the flood came.

Issues of regulatory compliance is a great blessing able so that a number of tapes a snapshot of the systems at the desired point of Zeit.Keine was may accidentally deleted question which may be tampered with the live data or a snapshot from the near-line system month end bands for the time required will have been sitting a copy of the data Nice and safe and with a lower power requirements as an always-on System.Wenn have the opportunity to use some of the tape systems such as LTO or T10000 WORM capability can then pass this trust developed.

Data recovery from tapes and disks

Plot some data to tape, and then click a Festplatte.Nehmen each- and -drop of six feet then try the ground, restore the Daten.Die hard drive works may, if you are very lucky, the band almost certainly funktioniert.Am worst is housing the band needed a bit of work to a data recovery specialist I, but in general it will be fine sein.Als what I prefer my backup archive on impact white on stored, it would be the band every time.

The point is, that the two disks for different purposes can different and designed sind.Disk-based systems give convenience, responsiveness and a priceless near line backup system, that the delay is smooth, otherwise, caused by minor operational errors.-based tape systems, but give a solid backstop for data security and a reliable data audit trail.

The answer to "Tape or disk?" is ideal more self zuschreibende "both".the named D2D2T (disk to-disk-to-tape) systems offer a mix of both technologies make use of speed and flexibility of for instant backup and recovery, but with the robust support of tape storage disk that add extra level of security.
